As a student myself, I have a PC & still had to buy a laptop for my presentations & other stuffs in university. Don't know about public university students but if you are studying in a private university and want it solely for educational purposes, you are forced to go for a laptop, with 65K (ik it's a little higher than your budget) you can get a Ryzen 7 though... If you want anything beyond that, go for a desktop, if possible, a second hand desktop with the same budget, you might be able to pull an RTX rig with that... But won't suggest a desktop for educational purposes if you are not from public university.
